RFsäteilyksi

RFsäteilyksi is a Finnish term that translates to "RF radiation" or "radio frequency radiation." It refers to electromagnetic radiation within the radio frequency range of the electromagnetic spectrum, typically spanning from about 3 kilohertz to 300 gigahertz. This type of radiation is a component of the electromagnetic field and is used in a wide variety of technologies, including radio broadcasting, television, mobile phones, Wi-Fi, radar, and medical imaging.

The interaction of RF radiation with matter depends on its frequency, intensity, and the properties of the material it encounters. At lower frequencies and intensities, RF radiation can induce electric currents in conductive materials. At higher frequencies, it can be absorbed by materials, leading to heating effects. The biological effects of RF radiation have been a subject of extensive scientific research.

International organizations and national regulatory bodies establish guidelines and limits for human exposure to RF radiation to ensure safety. These limits are based on scientific assessments of potential health risks. Public concern regarding the potential health impacts of RF radiation, particularly from sources like mobile phones and base stations, has led to ongoing research and public discussion. It is important to distinguish between RF radiation and ionizing radiation, such as X-rays or gamma rays, which have enough energy to remove electrons from atoms and molecules and can cause DNA damage. RF radiation is non-ionizing.
